It said the car appeared to have “lost control during an overtaking manoeuvre” and crashed into the stationary truck by the side of the road.
Pictures shared by the FRSC showed a wrecked car at the site of the crash, with a crowd of onlookers gathered around.
The Lagos-Ibadan expressway is known as one of Nigeria’s deadliest roads, with particularly heavy traffic at this time of year as many Nigerians living abroad visit for the festive period.
Joshua, who was born in Watford, has family roots in Sagamu – a town in Ogun state, south-west Nigeria, near the crash site.
He had been spending time in the country following his recent victory over American YouTuber-turned-boxer Jake Paul on 19 December.
Hours before the crash, Joshua posted a video to Instagram of him playing table tennis with another man. It is unclear exactly when or where the video was taken.
